Foods that Make It Easy to Add Protein to Your Diet

Foods that Make It Easy to Add Protein to Your Diet

There is probably no doubt that protein is an important part of our diet. However, supplementing it is not always easy. For example, many people still struggle with which sources are the best and where to find protein. That’s why we’ve compiled a list of foods that are literally loaded with protein. Some you may not expect to find among them at all.

Why is protein so important and how much protein do you need? 

Protein is one of the three essential macronutrients people need for proper body function. It is not only important for bone health, muscle growth and maintenance, or weight loss. It is also part of enzymes, hormones, genetic structures and defence structures such as white blood cells. Protein is therefore also essential for the immune system. Moreover, it can also help speed up your metabolism and promote regeneration.

According to the general recommendation, protein intake should range from 0.8 – 2 g of protein per kilogram of body weight (BW), depending on age, health status and amount of physical activity. For a 70 kg person, this is 56 -140 g. The upper interval could be followed, for example, by an active strength athlete who is dieting and wants to protect muscle mass from being burned for energy or would like to gain some muscle. The lower limit is more for people who live a sedentary lifestyle.

In order to be able to take in sufficient amounts of protein, you need to have protein-rich foods in your diet regularly. In our article, we will focus on readily available sources of protein that you can easily incorporate into your diet. For each of them, we’ll take a closer look at their approximate nutritional values, their beneficial content and also give you tips for some recipes. [1-3]

The top high-protein foods that can easily be included in your diet

1. Protein powder

It’s probably not surprising that protein powder is at the top of the list. It falls into the category of functional foods that have a beneficial nutritional profile and a positive effect on our health. Thus, you do not have to worry about it containing any dangerous substances. Among the most popular ones are whey protein powders, which are made from pasteurised milk, in which whey is separated from casein thanks to enzymes. It is then further processed to produce a quality protein with an optimal protein content. These make up approximately 70-90%. [4]

For vegans, there are plant-based protein powders, which typically have a less favourable amino acid spectrum. These include, for example, soy, rice, hemp, pea or multi-ingredient plant protein. So it’s up to you which one you reach for.

In addition, some proteins are enriched with other popular ingredients. This then underlines their functionality even more. These may include, for example, various vitamins, minerals, amino acids, digestive enzymes or fat burners. If you want to learn more about proteins, their origins, sources and functions, you should not miss our article How to Choose the Right Protein for Weight Loss or Muscle Growth?

Whey protein powder is so much more than just protein, see how it can improve your life in our article Whey Protein and Its Effect on Muscle Growth, Weight Loss and Health.

2. Peanuts

If you like to enjoy something good in front of the TV, you will certainly be delighted and pleasantly surprised by peanuts. Peanuts are among the foods with a high proportion of protein and healthy fats. They also boast a considerable amount of beneficial substances and micronutrients, such as magnesium, vitamin B3 (niacin), copper, oleic acid, resveratrol, phenolic acid and flavonoids. Thanks to their unique nutritional profile, peanuts may have an impact on our cardiovascular health, lower cholesterol and reduce the risk of developing type 2 diabetes. You can also reap these benefits with peanut butter. [22-24]

In both cases, however, beware of the high energy content. Similarly, especially with peanut butter, keep an eye on the overall ingredients list so that it contains as little ingredients as possible. For example, a 100% peanut butter that contains only peanuts and nothing else is ideal.

You may also be convinced to eat more peanuts because just one handful (about 28 g) will provide about a quarter of the recommended daily allowance of manganese and about a third of vitamin B9 (folate). A higher intake of folate is particularly important during pregnancy, as it affects the growth of germ tissues. [19] [24]

3. Chicken meat

Chicken breast is the holy grail of every fitness buff. It is a quality source of protein with minimal fat. In addition, they are carbohydrate-free but boast beneficial substances such as vitamin B3 (niacin), selenium and phosphorus. Their properties make them an ideal food for weight loss, even in the final phase of a pre-race diet. If we are concerned about taste and quality, it is ideal to choose meat from welfare farms. This is because we know the origin and the conditions in which the animal was raised. You may be surprised to learn that the meat of organic or free-range chickens also has slightly more protein (about 2 g). This is mainly because the animal usually lives longer and gets more exercise. [5]

But the breast is not the only part of the chicken that is rich in protein. Thighs or wings are also a great choice. However, these usually already contain more fat, especially because of the skin. If you want to reduce the proportion of this macronutrient, it is ideal to remove it from your meat.

Our tip: If you don’t have time or don’t feel like preparing meat for any other reason, canned chicken breasts can be a great option and can be eaten straight away.

4. Beef

Beef is a great source of protein, which varies by species in fat content and total energy. If protein is your main priority, it’s ideal to go for a high-quality beef back or sirloin, which are also popular with foodies. The downside, however, is the higher price, which may not be affordable for everyone. Less suitable and fattier are, for example, the leg, belly or flank. 

In addition to protein, beef is also a great source of haem iron. This is more easily absorbed than the non-haem iron typically found in plant foods. So if you want to supplement this mineral and you’re not a vegan, beef is a great choice. Iron deficiency could lead to anaemia, which is most often manifested by increased fatigue, poor breathing or pale skin. Women are more susceptible to anaemia as they lose iron from their bodies through menstruation each month. In addition to iron, however, other micronutrients such as vitamin B12 (cobalamin), zinc, selenium and vitamin B3 (niacin) are also found in beef. [6]

5. Pork

Even pork is a great source of protein and other micronutrients. These include vitamin B1 (thiamine), selenium, zinc, vitamin B6 (pyridoxine) and B12 (cobalamin). However, the disadvantage is often its higher fat content. With this type of meat in particular, it is also important to look at the quality and ingredients list and ideally choose a leaner cut that is lower in this macronutrient.

For example, pork tenderloin, leg or roast is a great choice. A fattier option is pork neck. Another interesting fact is that a 150g serving of pork tenderloin will provide the entire daily amount of vitamin B3. This is involved in the proper functioning of the psyche and nervous system and also helps to reduce fatigue and exhaustion. [19] [24]

6. Almonds

Unlike peanuts, almonds truly belong to the nut family. You may never have known that they in fact contain a decent amount of protein. What’s typical about them is their high proportion of healthy fats. However, we shouldn’t overdo it with those either, so it’s ideal to have a handful, for example, rather than the whole packet. In addition, however, they are a source of protein and will also win you over with their high fibre content, which is important for healthy digestion. You may also be surprised to learn that almonds have been associated with fertility since the time of the ancient Romans.

Moreover, nuts are rich in magnesium, potassium, manganese, vitamin E and other micronutrients. Even with almonds, there is no need to consume the nuts alone. You can also enjoy them in the form of a soft butter, which is great in porridges and desserts. And if you’re not a fan of almonds, you can give other nuts a chance too. How about trying pistachios, hazelnuts, walnuts or cashews? You can also enjoy these in the form of delicious creamy butters

7. Lentils

Lentils are a quality and affordable source of protein that is often overlooked. It also contains complex carbohydrates, fibre, and lower amounts of fat. This makes it ideal complex food. You can eat it as a side dish, use it as a base for a meal or liven up a vegetable salad with it. The great advantage is that vegetarians and vegans can enjoy it too. However, it is also rich in micronutrients. It is worth mentioning, for example, its high content of vitamin B9 (folate), B1 (thiamine), copper and iron.

However, there is not just one type. There are several types. You might be familiar with green lentils from the school canteen. Its disadvantage, however, is that it takes longer to cook and has to be soaked in advance. In these respects, it is competing against peeled red lentils, for example, which are ready in no time, are more digestible and do not require soaking. However, you can also find black lentils (beluga), which have a subtle nutty flavour.

And if you haven’t found a taste for lentils yet, you can try lentil chips or pasta for a side dish or salad base. Alternatively, you can also reach for other legumes such as beans, peas, soya or chickpeas. They are a great source of health benefits that support the proper functioning of the body. In general, it’s a great choice to combine legumes with cereals to increase the quality of the protein they contain and bring the amino acid spectrum closer to that of animal protein.

8. Tuna

Tuna is one of the popular marine fish with a high protein content and healthy omega-3 fatty acids. An optimal intake of these fish has been linked, for example, to cardiovascular health. It is also a great source of vitamin B12 (cobalamin) and vitamin D, which in turn is important for bone health and the immune system. You can eat it in the form of a delicious steak or make the preparation easier by using canned tuna in oil or in brine. You can add it to salads or make a delicious spread. [24]

But tuna is not the only delicious fish that is rich in protein, beneficial substances and healthy fats. Salmon, trout, prawns, sardines and other smaller fish species can also be a great choice, as they generally contain far less mercury compared to larger ones such as shark. However, you can also go for seafood.

9. Pumpkin seeds

Pumpkin seeds are another food that you would expect to be high in fat rather than protein. However, both are correct. They are rich in beneficial omega-3 fatty acids, but also contain manganese, phosphorus and magnesium. This is why they have an effect on the proper functioning of our muscles, nervous system and psyche.

In addition, pumpkin seeds also have a high content of protein and fibre. They are therefore a great food that should definitely not be omitted from your diet. However, pumpkin seeds are not the only seeds with excellent nutritional properties and interesting protein content. Chia or hemp seeds are also a great choice in this respect, especially for smoothies.

10. Tofu

Tofu is one of the most popular and highest quality sources of plant-based protein. It is made from soybeans and has a high calcium, manganese, copper and selenium content, which has an effect on, for example, the immune function and the maintenance of healthy hair and nails. However, the soya from which tofu is made can also have a good effect on our health. Specifically, it has been linked, for example, to positive effects on the cardiovascular system and a possible reduction in ‘bad’ (LDL) cholesterol levels. [7]

The energy value of tofu can vary considerably depending on the type. If it is in brine, it usually has a higher water content and, conversely, a lower energy value. However, you are more likely to see vacuum-packed tofu without brine, which has a higher energy and protein content. Therefore, the resulting protein and other nutrient content simply depends on the water content and nutritional properties of the soybean. Tofu, however, is not the only popular plant-based protein. Tempeh, which has a slightly nutty flavour, or seitan can also be a great choice. Both of these sources often contain more protein than the popular tofu.

11. Oats

Oats are another food where the protein content may come as a pleasant surprise. They are high in carbohydrates and fibre, but also contain phosphorus, copper, iron, selenium, magnesium and other beneficial micronutrients. However, the composition also includes powerful antioxidants called avenathramides, which help protect cells from oxidative stress. In addition, oats have been linked to a possible effect on lowering blood pressure, the risk of diabetes and cholesterol, thanks to their fibre content in particular. [8-10]

If you regularly have oats on your plate or in your breakfast bowl, you may find other alternatives useful. How about trying buckwheat or millet flakes too? You’ll find that they add a new flavour dimension to your meals.

12. Quinoa

Quinoa is a gluten-free pseudo-cereal with a high fibre content. In addition to quality carbohydrates, you will also be pleased to know that it will help with protein replenishment. In addition, it contains attractive amounts of copper and magnesium, which are minerals important for the proper functioning of the body. In addition, it contains many beneficial phenols, terpenoids and flavonoids, which have a number of physiological functions. For example, quercetin, which has antioxidant properties. It helps protect the body against oxidative stress and free radicals. Although its beneficial effects have been talked about especially in recent years, it is certainly not a new food. It has been part of our diet since the pre-Columbian period. The ancient Incas even considered it a gift from God. [11]

Before cooking, it is necessary to bear in mind that quinoa also contains so-called anti-nutrients, which are ingredients that can reduce the absorption of the contained substances. You can reduce the proportion of these undesirable ingredients by rinsing and soaking the quinoa before cooking. If you want to add other pseudo-grains to your diet, then amaranth or buckwheat should not be overlooked. [12]

13. Curd cheese

Curd cheese is another must-have in the fridge of all strength-training men and women. It is a universal food that can be eaten in a thousand different ways. The main reason it is so popular in this community is clearly its high content of slowly absorbed casein protein. This is also why, for example, bodybuilders eat it mainly before bedtime. During this time, the body has a longer fasting period, so this food is a great way to provide the body with nutrients during this time. Micellar casein can also be a great alternative to curd cheese.

Depending on your goals and preferences, you can choose how much fat you want in your curd cheese. The great advantage is that it is relatively low in lactose compared to other dairy products and so often does not cause digestive problems even for people with lactose intolerance. In addition, it contains beneficial probiotic cultures and calcium, which is particularly important for healthy bones. Other dairy products that are rich in protein include Skyr or Greek yoghurt with 0% fat.

14. Spirulina

Spirulina is a popular superfood. It is an extract of freshwater algae, which, thanks to its chlorophyll content, it captivates with its blue-green colour. It will probably also surprise you with its extremely high protein content (57.5 g/100 g). However, it should be noted that the recommended dose is usually up to 10 g. So you can’t count on eating it in larger quantities and using it as a primary source of protein, it serves more as a support for the body’s natural detoxification. It is also often associated with an anti-ageing effect. [25]

Micronutrients such as iron, copper, zeaxanthin or vitamin B2 (riboflavin) are much more valuable. Thanks to phycocyanin, it also acts as a powerful antioxidant. In addition, the results of studies suggest that spirulina may help to reduce bad (LDL) cholesterol levels. In a sufficient dose, it can then help to lower blood pressure. If you’d like to try other superfoods high in protein and other beneficial substances, reach for chlorella or green barley. [13-15]

15. Eggs

Eggs are food that almost everyone has in their fridge. But you may not even realise what a valuable source of nutrients they are. In addition to high quality protein and fat, we can also mention vitamins B2 (riboflavin), B12 (cobalamin) and selenium. In addition, studies have shown that eggs help to increase the value of ‘good’ (HDL) cholesterol.

Egg yolks in particular contain choline, which is used to boost cognitive abilities such as memory and concentration. Eggs also contain lutein and zeaxanthin, which are antioxidants that can promote eye health. The ingredients list of different eggs can vary slightly depending on what the hens have been fed. It is therefore ideal to at the very least avoid cage eggs, where hens generally have poorer living conditions. [16-18]

If you want to use eggs primarily as a source of protein with as little fat as possible, you may find it a great option to straight out buy egg whites. You can use them, for example, in omelettes or breakfast muffins.

16. Nutritional yeast

Nutritional yeast is a food popular especially among fans of plant-based diets. It does not contain active yeast, so it is mainly used as a seasoning to add a new flavour dimension to food. It can add a cheesy touch to dishes. Furthermore, it is high in protein and contains vitamins B2 (riboflavin), B3 (niacin), B6 (pyridioxine), B9 (folic acid) and B12 (cobalamin). You will also be pleased to find a high content of antioxidants such as glutathione and selenomethionine.

Thanks to its high protein content and relatively low energy value, cottage cheese is one of the most popular dairy products that definitely makes sense to include in your diet. It also contains a high amount of selenium, vitamin B12 (cobalamin) and calcium, which is important for bone and dental health. However, it also has an effect on the proper function of muscles, digestive enzymes and is important for normal blood clotting. The selenium it contains helps maintain healthy hair and nails. Cottage cheese can usually be found in stores in both sweet and savoury varieties, making it even easier to incorporate into your diet. You can use it as a quick snack with vegetables or fruit or as a base for spreads and summer salads.
